New signalling system to be tested on Tue, 28 Mar

New signalling system on North-South Line to
be tested on Tuesday night, trains to stop for 10 minutes

All trains on the North-South Line will stop on the
tracks for about 10 minutes at around 11pm on Tuesday (March 28),
so a new signalling system can be tested.

This is to facilitate the cut-over to the new system,
which will be tested for the first time during passenger service
hours.

About 30 trains will be in service during this
period.

The Land Transport Authority (LTA) and SMRT said that
in-train announcements will be made to inform commuters of the
temporary suspension in operations.

Once the new signalling mode takes over, train services
will resume, they added.

The LTA said it will evaluate the success of Tuesday
night's trial, which will run for the last hour of revenue service,
before deciding on further testing dates.

Mr Tan Yih Long, LTA's re-signalling project director,
said: "The results will help LTA decide when to extend trials to
longer service hours, and eventually the full switchover of the new
signalling system."

The upgraded signalling system is one of the key
projects to renew the ageing 30-year-old North-South Line. It will
allow trains to run at shorter intervals of up to 100 seconds,
instead of 120 seconds during peak hours.
